Description
there seems to be some problem in calcOpticalFlowFarneback() on i686 - (using packages from ArchLinux). Crosschecking with the same calling code and sample video it works on Linux 64bit, Mac 64bit and iOS 32bit. The erroneous results are quite apparent in the following video:

Hi, Hartmut!
To reproduce this we need a test sample with the wrong behaviour (and sample video too). Without this the ticket will be closed soon.

Seems there was some other stuff wrong in somewhere in the pipeline. But for whats worth it, here a small test rig:
